Black Box LE3700A-R2 manual How Do I Know It’s Working?, Power-Up Troubleshooting

CHAPTER 3: Installation

3.1 How Do I Know It’s Working?

If the EPS appears to be working (OK LED is blinking slowly) and the unit is connected to the network, there are various ways to confirm that the unit is visible to network hosts:

•If the EPS has an IP address, you can PING it from a TCP/IP host— the EPS should respond correctly.

•From a NetWare host, the EPSCON utility (provided on the enclosed NetWare utilities disk) will show available print servers (including the EPS) if you enter EPSCON with no options. See Appendix C for more information.

•From a Macintosh, the EPS should show up as a LaserWriter device under the Chooser. It will appear as a device named “EPS_xxxxxx_S1.” If multiple zones are running, it will appear in the default zone.

•From a LAT node (such as a terminal server) the EPS name will show up as an available service. It will also be visible from NCP or TSM, if the server name is added as a node.

Any of these methods will confirm that the unit booted successfully.

3.2 Power-Up Troubleshooting

If the unit does not display the welcome message or the LEDs do not appear correct, there are several possible errors:

1.Power-up diagnostic failure: the LEDs will remian in one pattern and you will not be able to use the console. This generally indicates a hardware fault that the EPS cannot continue past. The LED error codes are included in Appendix C; if the error is not a setup error, call Technical Support.

2.Power-up error detected: If the power-up tests detect a non-fatal error, the EPS will boot but will not try to load the Flash-ROM code. Instead, it will print a diagnostic screen to the serial port and wait at the “Boot>” prompt for user action. Note the error reported and try to correct the cause of the error. If the error is not obvious, contact Technical Support. Remember that the EPS must have a valid network connection to boot fully—this is the most common reason for boot failure. You need to change the first DIP switch if you are using the AUI port instead of the default RJ-45 10BASE-T port.
